Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutritional factors and bone growth. The risk period for esthetic changes in permanent teeth is between 20 and 30 months of age. The recommended level of daily fluoride intake is 0.05 - 0.07 mg F/Kg/day, which is considered of great help in preventing dental caries, acting in remineralization.
Treatments are -
1. Controlling the fluoride intake is the best preventive measure for dental fluorosis
2. Bleaching and enamel microabrasion techniques are conservative, and provide highly satisfactory results, without excessive wear of sound dental.
3. Microabrasion is carried out by rubbing an abrasive paste prepared with pumice stone and 37% phosphoric acid gel over the pigmented enamel surface, during 10 seconds, and then washing it in 20 seconds.
4. Bleaching is enough to improve esthetics results. Active agents of carbamide peroxide (10-20%) and hydrogen peroxide (1-10%) can be used on vital teeth
5. Composite resin and resin-modified glass ionomer are also used for treating discoloured areas.
6. Esthetic veneers
